To all whom it may concern." 7

Be it known that I, HowARn BnUon, a

citizen of the UnitedStates, residing at Baltimore,.in the Stateof Maryland,- have invented certain-new and useful Improve ments in Sealing-Bells .for Retort Stand- Pipes, of which theffollowing isa specification. I

This invention relates to improvements in sealing bells for standpipes of gas retorts, and the present application is a division of my co-pending application-for-patent filed January 7th, 1914, Serial Number 810,723.

7 bell about the standpipe end. v

Another object isto provide-improved One object of the invention is to provide improved means for sustaining theseallng means lor accurately adjustingthe lower I edge otthe sealing bell in the hydraulic;

sealing edge beneath the level of thesealing liquid, and a further object is to improve main whereby to uniformlysubmerge the the constructionn of sealing-bells and provide as great anjedge surfaceas possible i at the submerged bottom edge thereof un der which the gas may escape-in bubbles into them parallel. In the present mstance each-bell ispro the main.

With these,-a nd other objects inv view the invention is illustratedin the accompanying drawing, wherein Figure 1, shows arron't view of a portion of the hydraulic main; thejupper ends of: two standpipes enteringf-the mainand also shows in broken lines the improved sealing bells suspended in the main around the standpipe ends. Fig.1-2, illustratesthe same in vertical cross-section. Fig. 3, shows{ one of the detached sealing bells in perspective. Fig. 4, illustrates in top-plan, an-enlarged detail of the sealing bell sustaining means on the upper side or" the hydraulicmain, and Fig. 5, shows the same. 7

Referring-particularly to Fig. 3, of the drawing it will be noted that the sealing bell has a flat top plate 6, withja pluraliity of perforations7, therein. A boss8, encir cles each perforation at both the upper and lower side of thetop plate, as seen clearly in Fig. '5, of the drawing, and the-surfaces of these bosses are machined so asto" make a vertical sectional detail of '1 A knuckle22, havlng a convex undersurface SEALING-BELL FORRE'IORTSTAND-PilES; I

' vided front wall 9, a sinnlarlydependingsidewall 10,; while at tl1er.ear-and othersi'de, the walls 7 ofthe bellhave'straightdepending portions r 11, and 'outwardlyrextending' hollow p0r-.

edgesof the extension-are flush and in the same horizontal plane Bymeans-xofthisq, improved construction: of bell 'a very'con-fl sider'able loweredge surface is provided without materially increasi'ngthe size, of. the bell tselfflthereby afiording,a large edge surfacejbeneath which the gas may bubble.

Q'Ihe 'hydrauliemaim is; provided with a topplate 13, which has ,a plurality of cir-v v cular. enlargements ,14, on its upper side;

andeach enlargement has a;co-ncav'e recess 15, ;its upper side, ,asrclearly, shownin detail in Fig. 5, of the'drawing; An-ppenmay bepassed through-saidopening and haveits lower end engaged with .the top,6,- i

curately made and has a collar 18, near its lowerxend which seatsflon the machined upper surface. of one ;of f the bell bosses 8," while a" fn ut1 9,- screwsjonto the lower end of each boltand isf seated against'the boss on the under side of the .bel'lltopt In this way the v bolts'are secured to'thetop of the bell so 1 they willeextend upwardlvtherefrom-a-nd at a-right angle thereto.' Thebolts 17, are of of the bell beneath it. Each-bolt 17 ,is acuniforni length-land their upper ends 20,

are -flat tened lso-- as ,to beat ,aright angle now to be explained.

23, which Jaccurately fits 'the' recess like a "ball ina socket." P-llhislmutzkh has a squared head 24,} on its upper side through which.

a; screwthreaded perforation 25, centrally extends. cavity-26, eXtendsupwardly in "the center ofltheilmuckle body which cavwithresp ect".to the'length. Screw threads ity registers withtheopening 16, in=the-recess:ofthecircularjenlargement14. The. ir knuckle-cavity 26, is passed down over the upper end of the bolt 17., landthe threads in the perforation 25, are screwed onto the upper end of said bolt, during which operation the convex lower side 23, of the knuckle turns in'the concave recess 15. v

To insure accurate adjustment of the bell in the hydraulic main, itis only necessary to rotate the squared heads 24, on the knuckle. so as to raiseor lower the bolts 17,

which carry the bellpand as theboltsand the parts they coact with are accurately and uniformly made, a spirit level placed on'the I 7 flat upper ends of the bolts will determine the accuracy in -the adjustment of the. bell at the lower ends of the bolts.

The hydraulic nia in 'is providedcwith a seriesof cleaning pockets 27,.through which access to the main may be gained.

The standpip'es, or theupper sections 28,

thereof, preferably have a top cap 29, and

a front cap 30, both of which may be removed for cleaning purposes,'and in the present instancea branch 31, of each standpipe passes 'through the under side of the hydraulic main and has its'upper open end 32, terminating beneath a sealing bell of my lmproved construction.

It is immaterial whether the standpipe itself enters the hydraulic main or is provided with an upper section with a branch -31, that entersthemain, the fact remains that the outlet from the standpipe is covered by the improved sealing bella -Having described my invention what I claim. is 7 1; The combination with a standpipe of a gas'retort; a hydraulic *main with which the standpipecommunicates; a sealing bell over the discharge end of the standpipe; knuckles having a universalconnection with the hydraulic main and bolts. pendantly carried byv the knuckles and having their lower ends rotatably engaging the sealing bell.

' against the bell wall and 2. The combination with a standpipe of a V gas retort; a hydraulic main with which the standpipe communicatesg-a sealing bell over the discharge-end of the standpipe; knuckles having a universal connection with,

the standpipe communicates; a sealing bell over the discharge-end of the standpipe'and a plurality of rotatable bolts passing through the hydraulic main said rotatable bolts having their outer ends squared and dressed oli' accurately at a right angle to the bolt length and the inner ends of the bolts being rotatably connected to the bell.

4. The combination with a standpipe of a gas retort; a hydraulic main in which tie said projections and straight portions being in the same plane.

5. The combination with a standpipe of a gas retort; a hydraulic main with which said standpipe communicates; a sealing bell having a flat top and a plurality of hollow extensions around the side thereof, and a plurality of adjustable suspending devices engaging the top of thcbell.

'6. The combination with a standpipe of a gas retort; a hydraulic main" with which said standpipe communicates, and a sealing bell'in and'spaced from the top of the hydraulic main and over the discharge-end of the standpipe said sealing bell having a series of hollow extensions projecting therefrom which extensions are permanently closed on the sides and top.

7 The combination with a standpipe of a gas retort; a hydraulic main'with which the standpipe communicates; a top for said main saidtop having concave recesses therein; heads having convex surfaces to seat in the top recesses; a rod passing through each head-and a sealing bell in the main and sustained by: said rods.

8. A- gas sealing-bell having a top with sustaining perforations therein said bell also having a series of separated depending portions that'produce a series of hollow extensions.

9; gas sealing bell having a series of imperforate and separated hollow extensionsat its side and provided with means at its top for sustaining it.

1O. A gas sealing bell having depending portions in its side and hollow extensions also in its side that are'separated by the depending portions saidbell also having means at its top for sustaining it.

11. A gas sealing bell having a top with boss-encircled perforations therein,the

faces of the bosses at said perforations being parallel and said bell also having hollow extensions at its sides.

In testimony whereof I affix my signature in presence of two witnesses.
